Solved Confusing Error when getting Player.getName() through custom wrapper

Hey Bukkit Folks,

I am fairly new to bukkit plugin development, so go easy on me

I made a custom wrapper, in order to get additional properties to my players.

Here's my class for that:

Code:

public class CustomPlayer {
    public Player Player = myPlayer();
    public String Name = myName();
    public String CurrentJob = myCurrentJob();
    public UUID UniqueID = myUUID();
    public int JobExperience(String Job) { return myJobExperience(Job); }
    public int JobLevel(String Job) { return myJobLevel(Job); }
    public int WeaponExperience(String Weapon) { return myWeaponExperience(Weapon); }
    public int WeaponLevel(String Weapon) { return myWeaponLevel(Weapon); }
   
    private Player oPlayer;
  
    public CustomPlayer(Player P) {
        this.oPlayer = P;
    }
   
    public Player myPlayer() {
        return oPlayer;
    }
   
    private String myName() {
        return oPlayer.getName();
    }
   
    private UUID myUUID() {
        return oPlayer.getUniqueId();
    }
   
    private int myJobExperience(String Job) {
        return me.geekbuild.arvenyonRPG.Utils.Player.PlayerUtils.getPlayerJobExperience(oPlayer, Job);
    }
   
    private int myJobLevel(String Job) {
        return me.geekbuild.arvenyonRPG.Utils.Player.PlayerUtils.getPlayerJobLevel(oPlayer, Job);
    }
   
    private int myWeaponExperience(String Weapon) {
        return me.geekbuild.arvenyonRPG.Utils.Player.PlayerUtils.getPlayerWeaponExperience(oPlayer, Weapon);
    }
   
    private int myWeaponLevel(String Weapon) {
        return me.geekbuild.arvenyonRPG.Utils.Player.PlayerUtils.getPlayerWeaponLevel(oPlayer, Weapon);
    }
   
    private String myCurrentJob() {
        return me.geekbuild.arvenyonRPG.Utils.Player.PlayerUtils.getPlayerJobName(oPlayer);
    }
}

As you can see, in my constructor, I pass the player to my private variable in order to use it afterwards for different methods.
Somehow, I get an error when reaching for the custom playerstats through my wrapper:

Code:

        if (sender instanceof Player) {
            Player oP = (Player)sender;
            CustomPlayer P = new CustomPlayer(oP);
... (some code)
        for (String line : playerJobStats(P, "Lumberjack")) {
             P.Player.sendMessage(line);
        }

Method playerJobStats:

Code:

public ArrayList<String> playerJobStats(CustomPlayer P, String askedJob) {
        ChatColor gray = ChatColor.GRAY;
        ChatColor dgray = ChatColor.DARK_GRAY;
        ChatColor dgreen = ChatColor.DARK_GREEN;
        ChatColor green = ChatColor.GREEN;
        ChatColor gold = ChatColor.GOLD;
        ChatColor red = ChatColor.RED;
      
        String PlayerCurrentJob = P.CurrentJob;
        int PlayerJobLevel = P.JobLevel(askedJob);
        int PlayerJobExperience = P.JobExperience(askedJob);
      
        ArrayList<String> retVal = new ArrayList<String>();

        retVal.add(gray + "〖" + gold + "Job Stats" + gray + "〗");
        retVal.add(dgray + " Your " + dgreen + "[" + gray + askedJob + dgreen + "]" + dgray + " stats:");
        if (PlayerCurrentJob.equalsIgnoreCase(askedJob)) {
            retVal.add(dgray + " This " + green + "is " + dgray + "your current job.");
        } else {
            retVal.add(dgray + " This " + red + "is not " + dgray + " your current job.");
        }
        retVal.add(dgray + " Current Job-Level: " + gold + PlayerJobLevel);
        retVal.add(dgray + " Current total Job-Experience: " + gold + PlayerJobExperience);
        retVal.add(dgray + " Needed experience until next LevelUp: " + gold);
        retVal.add(gray + "〖" + gold + "Job Stats" + gray + "〗");
        retVal.add("");
        return retVal;
    }

Now, even though, I don't even reach for the PlayerName, I still get following Error:

Any idea, where my thinking error comes from? I am open for any suggestions. Still learning

Thanks in advance!

 

Force of habit. Is this relevant?

 

Thanks. That solved it for me. I was kinda brain afk, I guess
